IRIS Movie of the Day
At least once a week a movie of the Sun taken by NASA's Interface Region Imaging Spectrograph (IRIS) is posted by one of the scientists operating the instrument.

The Sun continues producing various activities around the peak of this solar cycle. This recent observation by IRIS captured more than one magnetic phenomena. A solar flare occurs in the active region near the west limb, producing two bright ribbons visible at the bottom left in this movie. At the bottom center in the movie, jets and spray surges occur recurrently above the limb. Off-limb coronal rains are also observed in the center of the IRIS SJI field of view, where cool plasmas move along magnetic field lines and are visible for hours.
